Objective

To verify the amount of radiation exposure to the eye of operators during endocardiovascular surgery (ECVS) in hybrid operating room (HOR), which increases the risk of cataracts in surgeons.

Methods

Fifty cases of ECVS (including 36 transcatheter aortic valve implantation and 14 thoracic endovascular repair) using the transfemoral approach performed from February 2020 to July 2020 were included. A measurement device was attached to the left side of the head of the operators and their assistants to measure the cumulative dose (CD) of intraoperative radiation exposure. The subjects were divided into the control group (Group C, n = 26), received conventional protection using the protective curtain in HOR and the protected group (Group R, n = 24), received conventional protection and protection sheet. The normalized CD by dose area product (CD/DAP) was evaluated.

Results

The CD/DAP of the surgeons was significantly decreased in Group R, averaging at 5.97 μSV/Gy cm² in Group C group and 4.40 μSV/Gy cm² in Group R (p < 0.01). Moreover, CD/DAP of the assistant was significantly reduced in the Group R, with an average of 1.87 μSV/Gy cm² in the Group C and 1.01 μSV/Gy cm² in Group R (p < 0.01).

Conclusions

The radiation exposure to the surgeon’s eye could be significantly reduced by protection sheet.

心血管内外科手术中辐射对操作者眼睛的影响及防护的重要性

客观的

验证在混合手术室 (HOR) 的心内血管手术 (ECVS) 中操作者眼睛的辐射暴露量，这会增加外科医生患白内障的风险。

方法

纳入 2020 年 2 月至 2020 年 7 月采用经股动脉入路的 50 例 ECVS（包括 36 例经导管主动脉瓣植入术和 14 例胸腔血管内修复术）。术者及其助手头部左侧安装了测量装置，用于测量术中辐射暴露的累积剂量（CD）。将受试者分为对照组（C组，n  = 26），接受HOR中的防护帘常规保护和保护组（R组，n  = 24），接受常规保护和保护片。评估了剂量面积乘积 (CD/DAP) 的归一化 CD。

结果

R组外科医生的CD/DAP显着降低，C组平均为5.97 μSV/Gy cm ²，R组平均为4.40 μSV/Gy cm ² ( p  < 0.01)。此外，R组助手的CD/DAP显着降低，C组平均为1.87 μSV/Gy cm ²，R组平均为1.01 μSV/Gy cm ² ( p  < 0.01)。

结论

保护片可以显着减少外科医生眼睛的辐射暴露。
